A normal test result should be 20–25 ml/s peak flow rate. A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for ...

These factors are usually related to lower urinary tract symptoms that affect the capacity of the bladder. Some patients with nocturia have neither ...
The x-axis is the volume of liquid and the y-axis is the intraluminal pressure of the bladder. In normal patients, the plot is a series of spikes whose local minimums form a non-linear curve resembling an exponential growth curve. The spikes correspond to the bladder contractions associated with the micturition reflex. The curve formed by the ...
